Re: How long to treat sprained ankle.
As long as it's swelling, I would go with ice. Go ahead and keep treating it until it feels better, or at least until the swelling goes down. You should also be trying to elevate it during the day when you can. You can try doing some gentle range of motion with it, just moving it in the four directions (up, down, in, out) gently. This will help stimulate blood flow. If it doesn't start getting better at all, though, you should go see a doctor to make sure that you don't have a small fracture somewhere.
